The first paragraph contains further facts and insight within both game and the character. There are no specific answers to solid release dates (as the developers/company may restate a shorter wait period or longer), how much gameplay time, or the plot of Edward Kenway's life besides the brief summary. The modern story which was previously belonging to Desmond Miles is now following the player who is a Abstergo researcher with DNA retrieved from William Miles, Desmond's father.
I can confirm to you that yes, Edward Kenway, is the name of the protagonist for "Assassin's Creed IV: Black Flag." (And to add more information) Our new nautical assassin is the father of Haytham Kenway, the secondary protagonist/antagonist from "Assassin's Creed III" but during the time frame in which the game is happening, Haytham wasn't conceived or born yet but only Jenny (Edward's first daughter and only child from his first wife.) Those that have read "Assassin's Creed: Forsaken," can get more in depth with Edward Kenway's family in the 'future (in terms for the game.)
There is no honest confirmation regarding Edward's personality or quirks except for those present in "Assassin's Creed: Forsaken" as the years have gone by since he was a pirate down in the Caribbean. I hope hope he isn't another Ezio (maybe a dab bit of similarities but you understand what I mean) as Connor Kenway's character was truly stoic but it represents him in its own unique way. Try sitting down and doing a character analysis on him; you'd be surprised on what you can pick up (and connect several events to several motives/personality traits.)
In honesty, Altair is my favorite as I assumed Ezio always got the better end of the stick and could carelessly choices and have them work out (but then again, he was evolved throughout the games into a great character.) Connor is a close second with Ezio and Desmond. Yes, I do qualify Desmond as an assassin and enjoy his character very much despite not much attention being drawn to the modern storyline. I just wished that Desmond could be sen as a main character too that can be voted on.
Overall, I can't wait for the new assassin to come rowing in! I'm still waiting to see if they'lll have "pirate subtitles" for the game. That'll be the best.
(Also, Blacki ,you have a typo in this segment: "...having been in three games, Assassin's Creed III, Assassin's Creed: Brotherhood, and Assassin's Creed: Revelations." )
